Working principle and program design of intelligent welcome device scheme development

智能迎宾器方案开发的工作原理和程序设计

This paper introduces the working principle of the scheme development of intelligent welcome device; Its MCU program development and design functions include: the function of automatically identifying people. Everyone who walks in front of it can pass its own induction detection, and then politely greet the successful person, such as "Hello, welcome" and other greetings to customers. At the same time, it can also remind the staff of the arrival of guests to avoid neglect.

principle

When someone comes from the front of the sensor, the sensor generates a positive half cycle signal. After receiving the signal from the sensor, the main control chip of the single chip microcomputer sends a command to trigger the voice generation circuit. At this time, the signal of the sensor works and sends welcome words.

Intelligent welcome device

Product function

1. Two way induction: when the human body is sensed to enter the door, it is "welcome", and when leaving the door, it is "thank you for coming";

2. Multi mode switching: one key switching. It is a welcome device during the day and an alarm at night;

3. Multi key control: control the, volume and mute of switching equipment mode respectively;

Main features

Direction identification: double induction windows are used to intelligently identify the direction of entry and exit; The volume is 4 levels adjustable; Adjustable voice delay (0 s, 2 s, 5 s, 10 s); It adopts 4cm high-quality loudspeaker with large volume, real and beautiful voice; Unique channel indicator; Thermal infrared induction detection, high sensitivity, double induction probe and double fuse; It adopts a variety of imported chips / integrated circuits with superior performance and low power consumption.
